5.1. CONCLUSIONS 
By the use of qualitative method, we draw some conclusions 
as follow: 
Metaphor, repetition, euphemism are the most frequently 
used stylistic devices in political speeches by Obama. Among them, 
metaphor ranked first, which was used the most in 50 speeches. 
Generally speaking, metaphor carried with it various rhetorical 
effects and strategies needed by the presidents for the purpose of 
persuasive and interesting speeches. Moreover we have found the 
distinctive features of metaphors in signaling affection and they help 
us identify the aesthetic in speeches and understand the speakers’ 
emotion. 
Each stylistic device has its own features and rhetorical 
effects so that it is the unique. Metaphor is preferred by the speakers 
thanks to its special effects on the audiences such as persuading

emphasizing, appealing to our imagination and creating a vivid image 
in the listeners/ readers’ mind. On the other hand, euphemism is 
actually able to create visual effects. Repetition is regarded the best 
way to express emotional attitude of the speakers or to emphasize his 
main messages. Rhetorical question is employed in speeches for the 
purpose of imposing a sense of support and approval on the audience 
5.2. IMPLICATIONS 
The present study provides a new angle to the study of 
English public speeches. The study surely provides a clear picture of 
the characteristics of Obama’s language features and it will also be of 
some benefit to comprehend the international situations and 
American politics. 
It can also help the readers to appreciate the English public 
speech better. This study will certainly provide a meaningful aid to 
improving our communication in English. Just as one of the elderly 
educators once said, “the best way to learn the most concise, forceful 
and refined English is to study public speeches in English”. Thus this 
study may be beneficial to the teaching of English reading. 
In addition, this paper will serve as a reference for further 
studies and provide some instructional guidance for students. The 
readers will probably employ these same methods of persuasion and 
presentation, including body language as well as actual word choice 
to strengthen their own communicative power. 
To some extent, this thesis is expected to be a valuable 
contribution to the teaching and learning of English stylistics in 
general and of stylistic devices in political language in particular. 
Furthermore, it also provides the learners with some useful 
techniques in writing speeches. Basing on the results of the study, 
we would like to put forward a number of implications.
